In order to achieve the above object, the utility model adopts following technical scheme:
External conical sleeve effective plug-in insulation plug, described insulation plug comprises:
Base, described base through screws connects with outer cone cannula tip;
Insulation plug body, described insulation plug body is by interface arrangment and base clamping, and entirety is set on the outer cone sleeve pipe that connects with base.
In the preferred version of this insulation plug, described interface arrangment comprises and is arranged on the jack on base and the plug with jack clamping, and described jack is arranged on the outer face of base, the inwall of jack is provided with draw-in groove and the aperture of jack is non-circular; Described plug is provided with the card relative with jack aperture on base, plug to assign on base in jack, make the card on it through the aperture of jack, and snap in the draw-in groove in jack after rotating, the free end of plug connects with insulation plug body inside top.
Further, described draw-in groove is annular slot.
Further, described insulation plug body is formed by the cast of silicon rubber one, and waters the ground hole of energy reliable ground in outer end.
The utility model is designed with Fast Installation interface arrangment by taper bushing side outside, make installation and removal process fast, convenient; The plug once-cast of simultaneously insulating is shaped, excellent insulation performance and inexpensive experimentation cost low.

Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 to 3, it is depicted as the structural representation of the external conical sleeve effective plug-in insulation plug that this example provides.
As seen from the figure, the external conical sleeve effective plug-in insulation plug that this example provides mainly comprises insulation plug body 1, screw 3, base 2 and plug 5.
Base 2 is fixedly installed on outer cone sleeve pipe 4 by screw 3, and plug body 1 is connected on base 2 by plug 5, and entirety is set on outer cone sleeve pipe 4, plays shielding action to high pressure.
In the program, to be coordinated with base 2 by plug 5 and form an interface arrangment, thus realize the quick despatch between plug body 1 and outer cone sleeve pipe 4.
Concrete, offer a counterbore 21 matched with screw 3 in base 2, screw 3 is as a securing member, and it is fixedly connected with the top of outer cone sleeve pipe 4 by this counterbore 21.Owing to being be spirally connected, can dismantle as required.
The screw of interior hexagonal specifically can be adopted for this screw 3.
The top of this counterbore 21 is as the jack 22 matched with plug 5, the inwall of this jack is offered an annular slot 23, the aperture 24 (i.e. counterbore 21 open top) of jack 22, as bayonet socket, it is non-circular, is specially a Long Circle (as shown in Figure 4).
In order to realize coordinating with the jack 22 on base 2, plug 5 entirety coordinates with jack 22, and it needs the top of insertion jack 22 is provided with the card 51 matched with aperture on jack 24, and its size shape matches with aperture, is Long Circle; The tail end (being namely positioned at the free end outside base) of plug 5 is for connecting plug body 1.
Time in the plug 5 of this structure jack 22 on inserted base 2, first its top upper clamp slice 52 is alignd with aperture on jack 24, then insert in jack 22, its top is inserted in jack 22 and stretches in interior six holes of screw 3, and card on top will through aperture on jack 24, relative with the annular slot 23 on jack 22 inwall; Rotate some angles by plug again, make the card of plug intersect with the breach of base and block, realize the clamping with base.
